What is SEC (- theta?
The reciprocal cosine function is secant: sec(theta)=1/cos(theta). The reciprocal sine function is cosecant, csc(theta)=1/sin(theta). And the 3 new functions are secant theta, cosecant theta and cotangent theta.
What is SEC equal to?
The secant of x is 1 divided by the cosine of x: sec x = 1 cos x , and the cosecant of x is defined to be 1 divided by the sine of x: csc x = 1 sin x .
What is the reciprocal of sin theta?
Answer: The reciprocalcosine function is secant: sec(theta)=1/cos(theta). The reciprocal sine function is cosecant, csc(theta)=1/sin(theta).
What is equal to Tanθ?
⇒ θ = nπ + ∝, where n ∈ Z (i.e., n = 0, ± 1, ± 2, ± 3,…….) Hence, the general solution of tan θ = tan ∝ is θ = nπ + ∝, where n ∈ Z (i.e., n = 0, ± 1, ± 2, ± 3,…….) Note: The equation cot θ = cot ∝ is equivalent to tan θ = tan ∝ (since, cot θ = 1/tan θ and cot ∝ = 1/tan ∝).
How do you find sin if you have cos?
Always, always, the sine of an angle is equal to the opposite side divided by the hypotenuse (opp/hyp in the diagram). The cosine is equal to the adjacent side divided by the hypotenuse (adj/hyp). What is the sine of B in the diagram? Remember opp/hyp: the opposite side is b and the hypotenuse is c, so sin B = b/c.
What is trigonometry formula?
Basic Trigonometric Function Formulas By using a right-angled triangle as a reference, the trigonometric functions or identities are derived: sin θ = Opposite Side/Hypotenuse. cos θ = Adjacent Side/Hypotenuse. tan θ = Opposite Side/Adjacent Side.
What is the formula for sin 2 theta?
The number sin(2θ) is the sine of twice the angle θ. It is almost never equal to 2sin(θ). that you can use in your problem. If you know that sin(θ)=x3, all you need to do to find sin(2θ) is to find cos(θ) and then use the Identity (1).
What is the value of 1 sin A?
0./div>
Is sin 1 the same as 1 sin?
Common Calculus Mistakes Example: Derivative of inverse sine. The notation sin-1(x) has been misunderstood to mean 1/sin(x). So sin-1(x) means the inverse sine of x, that is, the function that undoes the sine function. It is not equal to 1/sin(x).
What is the value of SEC a tan A?
∴(secA+tanA)(1−sinA)=cosA. Hence, the answer is cosA.
How do you solve sin theta 1?
Hence, the general solution of sin θ = 1 is θ = (4n + 1)π2, n ∈ Z. Therefore, either, 2 sin x + 3 = 0 ⇒ sin x = – 32, Which is impossible since the numerical value of sin x cannot be greater than 1. We know that the general solution of sin θ = 1 is θ = (4n + 1)π2, n ∈ Z. Therefore, x = (4n + 1)π2 ……………
What is SEC the opposite of?
We know that the secant is the reciprocal of the cosine. Since cosine is the ratio of the adjacent to the hypotenuse, secant is the ratio of the hypotenuse to the adjacent.
What is the value of sin theta into Cosec Theta?
Since Cosec theta is = to 1/Sin theta, Sin theta and cosec theta cancel out and cos theta is the answer…
What is the general solution of Sinx 0?
But, we know that if sin x = 0, then x = 0, π, 2π, π, -2π, -6π, etc. are solutions of the given equation. Hence, the general solution for sin x = 0 will be, x = nπ, where n∈I.
